What is an invoice?

An invoice is a formal payment request sent by a seller or service provider to a customer. It records what was supplied, how much is owed, when payment is due and how the customer should pay.

Who can use this invoice generator?

This tool is useful for freelancers, agencies, consultants, tradespeople, contractors, online sellers and small business owners who need a simple way to create professional invoices and download them as PDF files.

What should an invoice include?

A good invoice should include your business name, contact details, client details, invoice number, invoice date, due date, item descriptions, quantities, prices, tax, discounts, total amount due and payment details.

Why use a PDF invoice?

PDF invoices are easy to send, download, print and store. They also help preserve the layout of your invoice so the client sees a clean document rather than a broken spreadsheet or badly formatted message.

How to create an invoice

  1. 1Add your business name, address, contact information and optional logo.
  2. 2Add your client or customer details so the invoice clearly shows who is being billed.
  3. 3Enter your invoice number, invoice date, due date and purchase order number if required.
  4. 4Add your products or services as line items with quantities and unit prices.
  5. 5Add VAT, GST, sales tax, discounts, payment instructions, bank details, notes and terms where needed.
  6. 6Review the live preview, then download your invoice as a PDF.

Common invoice mistakes

  • Forgetting to add a clear invoice number.
  • Leaving out the payment due date.
  • Using vague line item descriptions.
  • Forgetting VAT, GST or sales tax where it applies.
  • Not including payment instructions or bank details.

Better invoices help cash flow

A clear invoice reduces confusion and makes it easier for a client to approve and pay. The more precise your invoice is, the less time you spend answering basic payment questions later.

For best results, use consistent invoice numbering, clear payment terms and simple descriptions that match what the client agreed to buy.

BizDocKit is being built as a free small business admin toolkit. More tools are planned, including quote generators, receipt generators, payment reminder tools and tax related templates for small businesses.
